Convergence

Published Mar 22, 2024

Definition of Convergence

Convergence in economics refers to the hypothesis or phenomenon where poorer economies’ per capita incomes tend to grow at a faster rate compared to richer economies. This concept suggests that over time, all economies should converge in terms of income per capita, assuming that they have similar savings rates, population growth, and technologies. The idea encompasses both ‘absolute convergence’, where all economies converge regardless of their starting conditions, and ‘conditional convergence’, which occurs among economies with similar characteristics and policies.

Example

To illustrate the concept of convergence, consider two countries: Country A and Country B. Country A is a high-income country with advanced technologies, while Country B is a low-income country with less developed technology. According to the convergence theory, over time, Country B should grow more rapidly than Country A, given that it can adopt the already existing technologies from Country A without the high costs of innovation. This adoption process allows Country B to make significant productivity gains, thereby increasing its per capita income at a faster rate than Country A, leading to a gradual narrowing of the income gap between the two countries.

Why Convergence Matters

The concept of convergence is critical for understanding global economic development and the potential for reducing income disparities between nations. It provides a framework for analyzing how and under what conditions poorer economies can catch up to wealthier ones. Policymakers, development economists, and international development organizations use convergence theories to design policies and programs that encourage technology transfer, improve education, and foster conditions that can speed up convergence rates.

Frequently Asked Questions (FAQ)

What factors contribute to economic convergence?

Several key factors can contribute to economic convergence, including:

• Technology Transfer: Easier access to existing technologies allows less developed countries to leapfrog stages of development.
• Human Capital Development: Investments in education and training can enhance productivity and innovation capabilities.
• Institutional Quality: Strong legal frameworks, transparent governance, and efficient public administration create an environment conducive to economic growth.
• Capital Accumulation: Increased investments in physical and human capital can lead to faster growth rates in developing countries.

Why do some countries not experience convergence?

Several reasons can prevent convergence from occurring, including:

• Lack of Institutional Quality: Poor governance, corruption, and ineffective legal systems can deter investment and hinder the adoption of new technologies.
• Geographical Disadvantages: Countries with limited access to global markets or those with challenging topographies may face additional barriers to growth.
• Technological Barriers: Inadequate infrastructure can limit the ability to adopt or adapt existing technologies effectively.
• Conflict and Political Instability: Wars, civil unrest, and political turmoil can destroy physical and human capital, derailing economic progress.

How can policymakers encourage convergence?

Policymakers can take several steps to foster convergence, including:

• Improving Education: Investing in the education system to build a skilled workforce.
• Enhancing Institutional Frameworks: Strengthening legal and institutional structures to support businesses and investments.
• Facilitating Technology Transfer: Creating policies that encourage the adoption of foreign technology and innovation.
• Promoting Economic Integration: Engaging in trade agreements and global markets to access new technologies and markets.

Can convergence lead to complete income equalization?

While convergence can significantly reduce income disparities, complete equalization of income across countries is unlikely due to differences in geography, culture, policies, and initial conditions. The concept suggests a narrowing of the income gap rather than an absolute leveling of income. Furthermore, as economies grow, new differences in technology, resources, and productivity levels can emerge, leading to divergences even among previously converging economies.
